991.2 Carrera S turbo failure

Hello all,

First post, and I'm asking about a problem *sigh* what a shame. Still, OPC handling it just fine so I'm relaxed about it.

Anyone had turbo failure on a 991.2 Carrera S? Mine have gone. 9 months and 7,000 miles only. My TVR was more reliable than this (actually, it wasn't). I couldn't tell you if only one unit had failed, but the car shut 'em both down (makes sense to me). At least one has an actuator failure that means entire turbocharger replacement is the only remedy. OPC replacing both turbos. Been driving for the last couple of weeks in a normally aspirated 3L car – it was surprisingly pleasant actually (I swear the exhaust note was better).

Other than that, I'm quite enjoying my first Porsche ownership experience [:)] Have a few club track days booked this year (Donington, Knockhill, Silverstone and Oulton), which I'm really looking forward to.

Cheers,

--Mark
 
What a shame! I was talking to a chap yesterday who has an actuator failure at 10k miles on a C2.

Not unusual though, I've been driving turbocharged cars for 15 years and have had two actuators go (Audi and Mitsubishi). Hope your OPC look after you!

That's actually good to hear Jim, would you believe. The OPC had made out this had never been heard of – which made me feel a) disappointed b) like I'd done something wrong. So now I feel slightly better about it [:)] Thank you!

I have a Macan for a few days. I'm not really an SUV kinda person, but for a gigantic barge it's quite impressive.

Two weeks it's been sat at the dealers now. Been waiting for a couple of o-rings to arrive from Germany since Wednesday last week. I thought all the parts were in when it was booked. Only irked a little.
 
We have a member in R1 with a 2017 turbo S. He has had to have both actuators replaced this year.
I’m sure he said the design left them rather exposed, hence the problem.

Thanks – it is actually comforting to know it's affecting others too. Mind, if it's a design issue is it likely to reoccur? I'm starting to have visions of TVR Speed Six engine issues [:mad:]
 
Finally, it's back! Only took two and half weeks. This time the service guy did say he'd 'heard of one other' 991.2 Carrera turbo actuator failure.

Car feels a bit quicker now ;-) And as much as the Macan was good for lugging stuff around, and don't get me wrong, an excellent vehicle, it really isn't a patch on a 911. These things just feel so special to be in. Very happy to have it back.
 
Hi, not sure of layout on the 991 but actuator failure on the 996 turbo is pretty common, my near side one has just snapped! They are extremely exposed to elements and rust through or size through lack of use , remedy make sure you get on boost as often as you can[:)]
 
Somewhat surprised to read of these problems. Sounds like engineering 101 (but then I'm an ex banker so what do I know?!).
 
Beginning of May 2018 I decided to treat myself to something special and bought a new Porsche 911 991 Carrera S Convertible from OPC Bournemouth.
After 532 miles, I was stopped driving into the village because smoke was pouring out the back. The dealer didn't believe me until I sent them the movie. Even then they sent 2 drivers out to collect it. They thought they could drive it back, (See what you think) I was unable to use it, I telephoned the dealership, twice no answer, I later emailed the dealer principle who arrogantly ignored me, we were due to tour France in so that never happened, 28 days after initially reporting it they had it recovered.
Most of you know I have a lot of technical knowledge which I had to use to diagnose the problems. When the car was returned, I complained about the lack of power, they had it back for another 3 days and said nothing was wrong.
I insisted that if a Porsche Macan S was quick as the Carrera 911 S, there is something wrong. A month ago I suggested that I suspected a fault with the waste gates on the turbo as I could hear a sound of leaking air during hard acceleration.
Not having got their attention
It wasn't until I contacted the group chairman before the dealer principle telephoned me (last week) then delegated it to the sales manager.
The Dynometer test took place Thursday 9th and proved the power was down by 70 BHP.
I drove to Porsche Dealership where I left it as the dash had lite up like a Christmas tree. They assured me that they would treat it with all urgency, I phoned on the 11th to check on progress, "we have just got it into the workshop so don't know what is wrong with it"
It is now 100 days since I bought and it has been off the road for 40 days. Believe me when I say that that once they had my cash they couldn't to hoots about service. I also wrote the dealer about the depreciation but that was ignored, everyone else I spoke with say they should paying me for the loss of use, whilst I wait for a permanent solution.
This is my second 911 in 10 months, what's happened to German engineering, I don't think it is a good as they make out, certainly the service has a lot to be desired.
Those technically minded out there should understand the chart on the right.
The Carrera S should produce 414BHP so someone has nicked the 70BHP.
I have been thinking of upgrading my wife 3 year old Boxster which we bought from the same dealer 3 years ago, will I buy another from them, I very much dought it, they have a long way to go to regain my trust.



Update on unreliable Porsche 911 S
I had a call today from the Franchise director of Porsche uk who said that the have ordered a new turbo and would be 3 days before they receive it. This afternoon I had a call from the dealership CEO who says that Porsche do not recognise Dynometer test (Rolling roads) but said the turbo is on order and could be with them tomorrow. He said that if that doesn't rectify the problem they will involve Porsche. I asked why they had't done that from the start, his answer was that there might not even be a problem with the car. I said that its normal for a Carrera 911S having difficulty in getting away from a VW Golf GTi. All they are interested in is covering themselves.
Does anyone know how I can put this on the Internet world wide to see if someone has an answer to a gutless new Porsche Carrera Convertible. Or if someone would do it for me, its now been 42 days of the road the best summer we have had for many years.
 
What a horror story
thats my local OPC I was considering a 991 next spring but now I’m not so sure....
 
I accept that the more technical cars become they are will go wrong. I thought this model was designed for me, but the dealers attitude is unbelievable.
I have spent £147,000 with them over the past 3 years which obviously goes for nothing.
I will be using a another dealership even if that means a bit further afield.
 
Geoff,

I appreciate your very valid disappointment with the PC but just be aware that the forum rules don't allow "naming and shaming" - although somewhat perversely, praise is allowed..!

You may want to sanitise your post to avoid a visit from the forum police.

Hope you get your problem resolved quickly and to your satisfaction.

Jeff
 
I think the problem could have something to do with the turbo being located behind the rear wheels and exposed to the elements, they still haven't fix the problem, I'm hoping I will get it back tomorrow.

 
$5 days now and just got it back.
Does anyone know what the BHP should at the wheels, I cannot believe it should be 344HP when Porsche advertise it as 420HP.
